Troubled bridge over water

Huge crowds of people have been blamed for causing the alarming swaying of London's first new bridge for 100 years, which was closed on its public opening amid safety fears.

The bridge is 100% safe, it's just that it does move when there are such large numbers of people crossing it

Police became concerned about the Millennium Bridge swaying violently in the wind under the weight of hundreds of pedestrians when it opened on Saturday morning.

Engineers made safety checks to the structure after it was forced to close briefly. A limit was subsequently imposed on the number of pedestrians allowed to cross the bridge.

A spokeswoman for the Millennium Bridge Trust said the swaying resulted from about 100,000 people crossing the span.

She said: "There are no safety problems with the bridge - we are simply the victims of our own success.

"We anticipated 10,000 people, but we think we had about 100,000 over the bridge. The bridge is 100% safe, it's just that it does move when there are such large numbers of people crossing it.

"We are satisfied we have now come up with a system to deal with these crowds if they occur again. We will have someone down at the bridge tomorrow to monitor the crowds."

A City of London police spokesman said: "From what I have gathered anybody who was a bit unsteady on their feet might have been in trouble."

"It was swaying in the wind and we closed it while we got in touch with the bridge's engineers and city engineers to see if it was safe," he said.

Designed to sway

A spokesman for architects Foster and Partners who designed the bridge with engineers Ove Arup and Partners said: "Because there was such a huge number walking all at once across the bridge, which is very unusual, there was a certain amount of swaying.

"The bridge is intended to have some movement. It's a suspension bridge - if there isn't movement there can be a problem."

The Thames partied on Thursday

Pedestrians had to wait for half an hour before they were able to continue crossing the bridge.

Those who had made it across before the closure said they had been surprised by the swaying sensation.

"The vibration was tremendous - I could feel the whole weight of the bridge swaying.

The closure, albeit temporary, was another embarrassment for a high-profile venture in London.

The Millennium Dome at Greenwich has had negative publicity since it opened, while the opening of the Millennium Wheel near Westminster was also delayed for a time, although it is now considered a success.

Earlier, celebrities joined charity fund-raisers to be first to cross the Millennium Footbridge, which links St Paul's Cathedral to the new Tate Modern art gallery.
